Rhizosphere Effect of Salix viminalis L. on Soil Enzyme Activity in a Wastewater Treatment Wetland
This paper presents the results how the root system of the common osier (Salix viminalis L.) affects the activity of selected extracellular enzymes (esterase, phosphatase, α‐glucosidase, β‐glucosidase, and leucine‐aminopeptidase) involved in the decomposition of organic matter in the constructed wetland, part of a wastewater treatment system. Soil samples from a zone affected by rhizosphere and a control sample were collected from three sampling sites located within the filter area: near the sewage inflow, in the middle of the plot, and at the end of the plot. The activities of the five extracellular enzymes were assayed by fluorescently labeled model substrates (4‐methylumbelliferyl and 7‐amido‐4‐methylcoumarin). Esterase activity was highest in the rhizosphere and control soil. The highest values of enzymatic activity were recorded in the rhizosphere soil at the wastewater inflow and decreased with increasing distance from that point.
